摘要
崇义上堡客家梯田2018年入选全球农业文化遗产。自此,上堡梯田的旅游开发兴起,包括兴建道路、民宿等。选取崇义上堡客家梯田旅游核心区一典型小流域,于2020年连续对该区域降雨量、径流和泥沙量开展自动监测。结果分析表明:受区域气候等影响,降雨多集中在5~9月,导致径流和产沙年内分配差异较大。次降雨分析则表明,受气候、地形地势等因素影响,降雨-产流-产沙之间未表现出明显的规律性响应关系。观测结果及分析同时表明,受旅游开发等人类活动的影响,小流域出口排泄的泥沙量增多,2020年为7000t/km2,达到强度侵蚀程度。研究旅游开发下的小流域产流产沙特征,将为重要农业文化遗产上堡客家梯田的开发与保护的协调发展提供科学依据。
The Shangbao terraces of Chongyi county is well known and was listed into the Global Important Agri-Cultural Heritage(GIAHS)in 2018.Since then,local tourism development came to a booming stage.Taking a typical small catchment in the tourism core area as the study object,an auto-monitoring system was set up to record rainfall,runoff,sediment in 2020.Results showed that the rainfall mostly took place from May to September,affected by the reginal temperature.The runoff as well as the sediment were distributed unevenly within a year,influenced by the rainfall and climate.Furthermore,a typical individual rainfall analysis showed that rainfall-runoff-sediment relations did not demonstrate a regular response.Results also significantly revealed that the erosion module of the catchment increased to 7000 t/km2,which was much higher than the average module of Chongyi county.Therefore,the study is helpful to provide scientific basis for improving the harmonious development of tourism and protection for the terraces.
